Giving up taking care of my mental health to take care of my physical health

Hi I have just begun trauma processing and my physical health has taken a decline. I already have chronic pain and now I'm having even more pain. I haven't been able to work the past few weeks and need to move because I can no longer afford rent. My sister said I could live w her but in doing so I will have to change therapists because it will be out of county and a three hour bus ride to actually get there even if I could stay w the same therapist. I have been in so much pain that I need help. I can't help but feel like I am losing out on important work for my mental health which has been severe the last few years. I'm mad that my body is causing me so many issues.
